Supreme Cutlass Posted June 23, 2005 Report Share Posted June 23, 2005 My brakes lack power, and I need to get them fixed so it can pass inspection. My primary suspect is air in the lines, but I don't get ABS lights pointing to unbalanced pressure. How do you bleed the master cylinder? :?: Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted June 23, 2005 Report Share Posted June 23, 2005 They make a tool that you can bleed your brakes with, just make sure you always have fluid in the master cylinder when you bleed your brakes, air will come out if there is any.

Supreme Cutlass Posted June 23, 2005 Author Report Share Posted June 23, 2005 There are bleeder screws on the master cylinder, how do you bleed the MASTER CYLINDER itself? If there was air in the individual brake lines, the ABS should have come on displaying unblanced pressure... right? Quote Link to comment Share on other sites More sharing options...
Supreme Cutlass Posted June 23, 2005 Author Report Share Posted June 23, 2005 does it work like bleeding calipers? SOMEBODY'S GOT TO KNOW!??! Quote Link to comment Share on other sites More sharing options...
cutlsp Posted June 23, 2005 Report Share Posted June 23, 2005 normally air gets into the system via opening it. the way to bleed the brakes is right rear, left rear, right front, left front. make sure you top off the fluid as you go and use a bleding system with a clear hose so you can see what your doing. also helps make sure you get the air bubbles out of the system.

19Cutlass94 Posted June 24, 2005 Report Share Posted June 24, 2005 Since your master cylinder is on the car, you have to bleed the brakes like you normally would, The bleeders that are on the master cylinder are for when it is brand new, to fill it with fluid.

Supreme Cutlass Posted June 24, 2005 Author Report Share Posted June 24, 2005 My service manual says you can use them to bleed it, just doesn't say how. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted June 24, 2005 Report Share Posted June 24, 2005 Because you bleed the master cylinder when its new, to fill with fluid so that its easier to bleed the whole system once installed. But how you bleed the master cylinder when its new, you run tubes from the bleeders to the fill, then you have to use a "pump" like where you start to draw the fluid from he fill into the cylinder, then pinch the tubes so what you just did, doesnt get reversed. I know its not the best explination but thats how you do it when its new. If that helps any, but since its on the car, I duno if you can do that or not.
